LCL Interfaces Changes

LCL Changes

IDE Changes

  • Added IDE macro $(OutputFile) for the outputfile of the project. This usually corresponds to $(TargetFile), except when having a host application, in which case $(TargetFile) is the host application, while $(OutputFile) is the project executable (or library).
  • Codetools support for anonymous functions
  • "Close tabs to the right" in Source-Notebook

IDE Interface Changes


  • Spotter: New IDE addon, showing a search list of all IDE commands.
  • TAChart: New property "AllowPanning" to turn built-in panning on/off.
  • TAChart: Property editor for TSeriesPointerStyle.
  • AnchorDocking: New button to minimize a docked site.

Changes affecting compatibility


LCL incompatibilities

TMaskEdit: hexadecimal and binary characters

Mask support for hexadecimal and binary characters was added (this is a Lazarus extension, Delphi does not support this).

  • Old behavior: the characters 'h', 'H', 'b' and 'B' had no special meaning in the EditMask property
  • New behavior: these characters now are mask characters for hexadecimal and binary input respectively.
  • Reason: nice to have feature (QT5 supports it natively).
  • Remedy: if you need one of these characters as a literal in your EditMask: escape them with a '\'.

Components incompatibilities

TAChart: Chart.AllowZoom changed

The property AllowZoom of TChart is meant to give the user the chance to turn the builtin zooming feature on or off.

  • Old behavior: AllowZoom operates also on an external toolset.
  • New behavior: AllowZoom is effective only for the built-in toolset.
  • Reason: More consistent handling of properties
  • Remedy: Use the property Enabled of the external zoom tool to switch zooming off, or don't add a zoom tool at all.
